To improve spatial resolution, positron emission tomography (PET) systems are being developed with finer detector elements. Unfortunately, using a smaller crystal size increases intercrystal Compton scatter and X-ray escape crosstalk, causing positioning errors that can lead to degradation of image contrast. We investigated the use of extremely thin ( 300 m) lead strips for passive shielding of...

Uncontrolled exposure to X-band frequency leads to health damage. One of the principles of radiation protection is shielding. But, conventional shielding materials have disadvantages. Therefore, studies of novel materials, as an alternative to conventional shielding materials, are required to obtain new electromagnetic shielding material. Therefore, this study investigated the electromagnetic s...

Advances in textile materials, technology and miniaturization of electronics for measurement instrumentation has boosted the development of wearable measurement systems. In several projects sensorized garments and non-invasive instrumentation have been integrated to assess on emotional, cognitive responses as well as physical arousal and status of mental stress through the study of the autonomo...

Introduction: The affinity of oxygen for both gaseous and solid phases makes it and its isotopes important tracers of redox conditions and isotopic reservoirs in the solar nebula. The oxygen fugacity (fO 2) recorded by chondritic meteorites ranges over several orders of magnitudes, from very high values needed to explain such minerals as ferrous olivine in ordinary and carbonaceous chondrites t...

Cloth simulation has a long history, starting almost three decades ago. Thanks to the continuous increase of computation speed of computers, real-time simulation of clothes has become very recently possible. The research on real-time clothes has really begun few years ago when researchers have started simulating simple garments such as flags or tablecloths. Nowadays, the research aims at propos...

A blanket concept made of SiCf/SiC composite and utilizing Flibe as coolant and tritium breeder has been developed and integrated with the magnetic intervention system. To achieve tritium self-sufficiency, a 1 cm thick Be insert is utilized in the first wall coolant channel. All magnet, vacuum vessel, and personnel shielding requirements can be satisfied. The nuclear performance parameters of t...

The downfield shift of the NMR signal of the bridging proton in a H-bond (HB) is composed of two elements. The formation of the HB causes charge transfer and polarization that lead to a deshielding. A second factor is the mere presence of the proton-accepting group, whose electron density and response to an external magnetic field induce effects at the position of the bridging proton, exclusive...
